1. A process for forming a composite fluid stream comprising:
mixing a stream comprising a plurality of fibrous elements with a stream of particles exiting a nozzle in a machine direction having a range of particle sizes;
wherein the stream of particles exhibits an injection angle that is substantially non-vertical towards a collection belt and oriented in the machine direction of the collection belt;
wherein the stream of particles has a substantially lower air velocity than the stream comprising a plurality of fibrous elements, resulting in a bent trajectory of particles towards the collection belt;
wherein the bent trajectory of larger particles in the stream of particles exhibits a substantially larger turning radius towards the collection belt compared to smaller particles, resulting in the larger particles being embedded in the fibrous elements at a further distance in the machine direction versus the nozzle, and the bent trajectory of the smaller particles of the stream of particles exhibits a substantially smaller turning radius towards the collection belt, resulting in the smaller particles being embedded in the fibrous elements at a shorter distance in the machine direction versus the nozzle.
